HVAC – Is H2o Cure Needed?

HVAC – Is H2o Cure Needed?

Drum-Kickers, Soap Salesmen…they have been known as quite a few matters. Water Remedy experts (in all probability the title they like) are in all places. As a mechanical contractor, we have experienced many knock on our door. With most massive industrial properties and industrial amenities in Memphis utilizing water cooling/heating mechanical equipment, this marketplace is hugely competitive, but is water treatment seriously important? In this edition of Mechanical Matters® I am likely to reply that incredibly problem and explore various other vital specifics about h2o treatment companies.

In this version I want to remedy 3 issues with regards to water treatment:

Specifically what is h2o cure and is it required?

How does poor drinking water remedy services outcome mechanical machines?

Are there vitality cost savings with drinking water treatment method?

1. Particularly what is water remedy and is it essential?

Water cure describes a approach employed to make drinking water additional appropriate for a sought after close-use. These can consist of use as consuming h2o, industrial processes, healthcare and numerous other takes advantage of.
The purpose of all h2o treatment method is to take away existing parts in the water, strengthening it for subsequent utilization. (Wikipedia.org)

In the mechanical business water therapy is a strategy made use of to optimize most water-primarily based mechanical and industrial procedures, this sort of as: heating, cooling, processing, cleansing, and rinsing, so that functioning fees and threats are diminished.

Most h2o treatment programs consist of water softeners, inhibitors and other chemical compounds needed to ‘treat’ the h2o in buy to attain the sought after disorders for mechanical use and heat transfer. Goods employed to preserve good drinking water circumstances are frequently fed routinely by complex products straight into a chiller or boiler’s water. Drinking water is employed for both equally cooling and heating in big business creating apps. In most industrial environments drinking water is utilized for cooling manufacturing equipment or an component to producing a item. How the h2o is applied will figure out what variety of therapy is necessary.

Most water therapy corporations use exam kits and chemical dispensing devices which have produced the use of water cure chemical compounds in chiller, boiler and cooling-tower techniques considerably easier. But notice to particulars, this sort of as how frequently techniques are analyzed, is essential to system performance. The suitable water therapy chemistry at the right time is terribly crucial simply because even minor troubles can create big expenses.

Final 7 days I sat down to breakfast with Gary Reynolds and Bob Schubert of Garratt Callahan. They are water treatment ‘specialists’. Gary and I have labored together with numerous mutual shoppers. Their interest to depth, client service and extensive knowledge of h2o remedy is why numerous buildings in the Mid-South are in superior hands with Garratt Callahan. In our conference they presented me with some great details about the value of water cure, the consequences of weak provider and matters to look for in selecting a service company

2. How does poor or no service influence mechanical equipment?

Incorrect Drinking water Cure or no treatment method at all will improve your energy consumption and working value when decreasing your mechanical equipment’s efficiencies and lifetime expectancy. A well made and executed drinking water remedy program is highly crucial to the procedure of any steam boiler, centrifugal chiller and cooling tower. All 3 of the units revealed under use h2o for cooling and heating.

Bad h2o therapy allows h2o interact with the surfaces of pipes and vessels which consist of it. Steam boilers can scale up or corrode, and these deposits will necessarily mean far more gas is essential to heat the very same quantity of drinking water. Cooling towers can scale up and corrode, but left untreated, the heat, filthy h2o they can have will encourage microbes to mature, and Legionnaires’ Sickness can be the fatal consequence. The condenser tubes inside a chiller and other water cooling tools can also scale up and corrode as a result blocking good heat transfer. Enhanced power use and bad cooling general performance is prevalent final result in inefficient h2o cure.

Water cure can frequently be classified as ‘low-tech’ and unglamorous. Nonetheless, the ideal substances, proper chemical feed machines, and a dedicated provider service provider is important to your mechanical products and must be ‘treated’ with top rated precedence.

3. Are there electricity price savings with h2o treatment?

Remedy Value: Professional drinking water remedy can reduce your water, strength, and routine maintenance charges significantly. Maybe most important of all, it can help save you the price of correcting or replacing tools which is been weakened by insufficient drinking water cure – which includes the downtime and misplaced earnings usually related with solving these problems.

The illustrations of drinking water treatment method ROI (Return of Investment decision) demonstrated under present how incredibly slender layers of deposited material from badly handled water can drive up power prices.


System: 1,000 ton chiller

Procedure: 12 hrs/day, 365 times/12 months

Price of electrical energy: $.10/kWh

Scale thickness: 1/32 inch

Elimination of 1/32 inch of scale saved $15,018 for each yr.

Organic Fouling

Process: 1,000 ton chiller

Operation: 12 hours/working day, 365 times/12 months

Charge of electrical energy: $.10/kWh

Bio-film thickness: 1/1000 inch

Elimination of 1/1000 inch of bio-movie saved $26,834 for each calendar year.

“As minor as 3/16-inch of scale can lead to a boiler method to use 38 p.c a lot more gasoline. The most minuscule amount of dissolved oxygen in the drinking water also implies a technique could be headed for corrosion troubles. And even a slender layer of bacterial slime in chiller tubes can considerably influence warmth-transfer effectiveness.”

Wrap Up:

As mechanical contractors we are no strangers to the significance of water procedure. On the other hand, following studying and producing this post I can assure you that I am considerably extra educated about the necessity and edge to possessing a good water remedy application.

In this edition Mechanical Matters®, I mentioned three crucial points about chemical water cure. 1st we realized the definition of h2o treatment method and its use in the mechanical marketplace. 2nd, we acquired that drinking water cure is unquestionably vital, and devoid of it your mechanical products will endure. Final we discovered how right water procedure will save power, and finally maximize your bottom line.
